When the distance between two charged particles is halved the coulomb force between them becomes:
Correct answer: B. Four times of the initial force
- A. One fourth of the initial force
- B. Four times of the initial force
- C. Double the initial force
- D. One-half of the initial force
Explanation
When the distance between two charges is doubled, then the force among them will become one- fourth time.F= kq¹q² ( 2r)²= kq¹q² 4r²F = 4

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
